AVR32 Studio 2.1 Linux projects have a slightly different build system compared to what was delivered earlier releases. Unconverted projects except for Linux executables, will build and work as usual but build options cannot be changed unless the projects are converted to the 2.1 toolchain.
Conversion will not be performed automatically so in order to convert do the following:
Shared/static libraries must be converted in two steps. First from 1.0.0 to 2.0.1 then from 2.0.1 to 2.1.0.
No changes has been made to the Standalone toolchain.
